Background

In the hydraulic and hydroelectric engineering, the water retaining building greatly changes the living environment of the fishes, the original continuous and intercommunicated ecological space is changed into the ecological space with unidirectional information transmission due to the rapid increase of the water flow drop, the seasonal migration and spawning of the fishes are blocked, and the genetic diversity of the fish population is lost and the quality of the economic fishes is degraded. Thus, research and manufacture of fish passing facilities are of great importance for protecting fish resources and restoring ecological environment.

In the process of constructing the fish passing facility, the lifting operation of the fish passing facility is one of indispensable important works. At present, most of the lifting function of fish passing facilities utilizes a self-unhooking lifting hook which is relatively common in the market, such as a remote control wireless automatic lifting hook of Elebia company. Elebia, the lifting hook is adsorbed on a matched special lifting ring by utilizing electromagnetic force, and then the main hook is controlled to turn over by controlling a motor (the motor is connected with the main hook through a gear pair), and the special lifting ring is inserted, so that an automatic grappling hook is realized; when unhooking, the special lifting ring is adsorbed by utilizing electromagnetism, and then the main hook is controlled to turn over by utilizing the remote control motor so as to separate from the special lifting ring, so that unhooking is realized. However, such hooks are expensive, increasing engineering investment; in addition, such hooks can be subject to electromagnetic contamination and can present a potential risk to the fish that are moving to spawn.

In summary, how to design a crane for fish passing facilities, which can not only give consideration to fish safety, but also reduce cost and has universality, is important to fish passing facility engineering.
